Patent number: 8024070Abstract: The present disclosure provides a fixed point stabilization device for a legged mobile body having a generating mechanism for generating a fixed point. The present disclosure also provides a fixed point stabilization device for a legged mobile body comprising a stabilizing device for stabilizing the fixed point in accordance with a leg grounding position of the legged mobile body. The fixed point is generated by inputting a predetermined constant torque to a joint of a leg of the legged mobile body on the basis of the energy balance in the legged mobile body, leg switching, and a leg swinging motion. The fixed point is stabilized globally by keeping the leg grounding position of the legged mobile body constant using a stopper.Type: GrantFiled: June 8, 2006Date of Patent: September 20, 2011Assignee: Nagoya Institute of TechnologyInventors: Akihito Sano, Hideo Fujimoto, Yoshito Ikemata

Patent number: 7984659Abstract: A measurement device can detect a degree of bending of a linear body with a sensor when compressive force in a direction of longitudinal axis is applied to the linear body as a result of contact of a tip end of the linear body with an obstacle. Then, the detected degree of bending of the linear body is converted to compressive force in the direction of longitudinal axis applied to the linear body based on predetermined correlation between the degree of bending and the compressive force, so that presence of an obstacle in a direction of travel of the linear body can be sensed based on increase in the compressive force. In addition, as the same measurement device is applicable to linear bodies of various shapes and materials, cost effectiveness is achieved.Type: GrantFiled: March 19, 2007Date of Patent: July 26, 2011Assignees: National Universtiy Corporation Nagoya, Institute of Technology NTN CorporationInventors: Hideo Fujimoto, Akihito Sano, Yoshitaka Nagano
